" ate f This "invention relates to-What Iterm a Acop bagger for use in textile plants such fasr-ug and 1carpet rfactories. 'lts purpose is to -facilitate.:the :assembly and vbagging Vof cops which, as 'is l.understood :in the iindustry, are `coils of thread or yarn Wound on spindles. They are formed -on winding machines and, upon .delivery therefrom, -they :are customarily'bagged for convenienthandlingand transporting to -other 'machines .employedin-Ithe process -of vmanufacture of rugs and carpets or fother Vtextile products.

`The .principal .object v-of vthe 'invention is @to r:provide `an efficient and easily operateddevice or Vmachine l'for-this purpose.

A lfurther object is to provide'finsuch vaffmachine'means ,whereby the cops may be compressed-ntoga tight fbundle and .enclosed within a wrapper lor bag which may :be readily .closed over thebundle :and fastened :before yremoval of the `bundle from the machine.

Another object of the invention is toprovide .an apparatus of thischaracter which can =beiiloaded and operated conveniently by a single operator. A-'.l`o this :end-'thefapparatus employs an actuating leverarm'ofspecial `construction which is :easy to operate and Amay be :actuated/if desired, by .a foot pedal, leaving the-operators fhands and arms free for handlingnthecops :and'emanipulating the-edges .of the wrapper .to .closetheg-same .and fasten them .together 'by means :of `snap-.on fasteners y.or other .appropriate ifastening idevices.

.A stillurthertobject .of Atheinventionis .cto provide .fan apparatus for the purpose 'stated which isi-so constructed that the compression .of vthevcops -is accomplished :by a wedging 4mechanism through 2.which `:powerful leverage may `be v applied without undue exertion ontherpart .of .the operator.

`Other objects :and `advantages of fthe rinvention vxwill Vbe apparent from the *following description, vtakenin rconnection with the accompanying drawings, lin which:

In lthe preferred .embodiment of rthe invention "illustrated by way ofexample in said drawings, the apparatus is shown 4as mounted .upon a base 111 to which a stand 12 comprisingtwouprights .13 and a steel pipe'13 arises, -said `uprights being secured -to thebase by angular yfoot pieces 14 and -hexagon head cap .screws '15.

A tubular sheet metal frame 16is attached-tothe uprights 13 by means .of capscrews 1'7 and has a wedging 2,891,365 .Patented June 23, 1959 .inner portion .18 ofgenerally .concave'formation, which is best 'shownin'Figs 1, 4 and '5.

Disposed within .the concavity 18 .is the above-mentioned cop compressor, which is generally indicated by 'the .numeral 19. This compressor comprises two sheet metal wings or walls V21 which are hinged together at their .lower central .portions by ajhinge pin T22. A pull rod .23 is .connected to, and .extends downwardly from,

.said .hinge pin .through the ,pipe I313. At its lower end said rod is.pivotally .connected with an-actuating lever .arm .whichis generally indicated .at 24 in .`Fig.;2. VThe attachment .is .eiiected .by means of a clevis 25 which is best shown inFigs 7 Yand 8. 'The lower end ofthe rod-23 .is .threaded .and is screwed .into a socket portion 26 of .said devis. The lowerpart 27 ofthe clevis is bifurcated -andfstraddles .an upper leverarmzforming .apart ofthe lever arm structure .24, being connected to said arm'28 `byahinge pin-29.

@Said arm 28 is hinged at 31 .to a bracket32 arising 'from the base' 11 and attached thereto Yby. an angle member '32', anda second lever arm, numbered 33, is disposed yimmediately below .and parallel .to .said arm'28, .said arm 33 connected. atits lower .end with .a cap screw '42.'xedly secured .to. thebase structure.

Pressure arms 43 are vconnected-at .their inner ends by pivot pins 44 to upper end portions 45, of channellfor- .mation, .of ,the framelgand at .their .outer .ends said arms are pivotall-y connectedbyrods 46, curved-straps 47 vand wing nuts 48 to -the .outer .portions ofthe cop compressor members 21. Y

.A vcanvasstrip 49 maybe .placed inside- .the sheet metal :members 21 of ithe .cop compressor .19, guide .pins .'51 .being provided to'hold :said strip close .to .theinterior of Said members. The ends of .the .strip may .be extended around the outer .edges of .said .members 21 and clamped :.bymeans .of toggleeaction clamps .52 againstrolled kportions ofthe curved attachment .straps iii-.surrounding the rods 46. :Said .clamps are provided with hand-pieces '53 Y'for manual .operation thereof to grip .or .release .the .ends

.of thecanvas .strip (which ultimately .forms the'bag or wrapper), .and inwardly from .the ends .of the strip .snapon fasteners 54., 54 are provided for .closing the ends together zbefore .the package'isremoved from .the machine.

Vertically disposed disks .55am-.provided .on .tbe .members "2.1 .at .-the .rear side .of the machine -to .provide a .backing .against which the cops, which are identiedby .the numera1'56,.may .abut when being placed in the .bag- .forming strip 49` that is disposed within the compressor.

In use, one or more .of .the machines of 'my invention may be placed near the discharge end of each .cop

, Winding machine in the factory. An attendant, having .placed anoanvas strip (formed .as above described) .in

the :compressor `element of the machine, with the latter Y.open and the ends of the .strip heldas shown .in Fig. 1

ofthe drawings, places-the .cops .in `the compressor. The proper -positioning .of them therein is facilitated Eby the :backing disks .55,.against which .one end .of .the copsmay fbe pressed.

At one or `more .stages as .the compressor iills .up the cops may bepreliminanily compressed by manipulation -of the pressure arms 43 by means .of the hand levers 55 .and the compressor wall `elements .2.1 will stay in their adjusted position. When the package -zhas nbeen -loaded to capacity, the attendant steps on :the footpedal 38 and 3 v presses it down against the force of the spring 41. As the compressor wings or walls 21 are moved downwardly they will be closed by wedging action against the inner walls of the concavity 18 of the frame member 16 and brought to the closed position substantially as shown in Fig. 4.

The construction of the lever arm structure 24, with the two separately hinged levers 28 and 33 pvotally connected with the foot pedal, facilitates the operation of the mechanism and permits the foot pedal to remain in horizontal position as it is moved up or down.

The nal increment of the closing movement of the wings or jaws 21 is eifected by the pressure arms 43, through manipulation of the levers 53. With the parts in the position shown in Fig. 4, the ends of the canvas strip may be released, by slight movement backward on their pivots, of the arms 53, thus raising rollers 57, which form a part of the toggle-action clamps, from the position in which they hold the ends of the strip in pressure contact with the pressure arm attachment elements 46, 47. The operator may then manually press the female and male snap fastening elements 54 and 54 together to close the bag, thus making a compact and easily handled package as shown in Fig. 9.

The package may be withdrawn from the open end of the compressor after the pressure has been relieved suiciently for this purpose.

It will be evident that after release of both the foot pedal 38 and the pressure arms 43 the spring 41 Will return the compressor elements to their upper and open position shown in Fig. 1.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but that various changes and modifications may be made in the particular embodiment thereof without departing from the spirit and scope of the invention.
